Healthy postural alignment is an easy feeling throughout your musculoskeletal system. But if you do most of your activities of daily living with poor body mechanics, or are injured or stressed in any way, this ease may well be replaced with muscle spasm and spinal misalignment. Fortunately, there are ways to address the alignment of bones and their effect on joints, muscles, and/or nerves. You might even get away with doing some of it at work. Or, you could try some desk exercises.
